FLANGE-PIN REMOVER.

Application filed August 19, 1926. Serial No. 130,257.

plate upon a base block.

Another object of the invention is to providethe base block with a plurali y of cells to contain flange pins of dillerent sizes, and to equip said base with a slidablo cover "for the cells, said cover having a tional connection with the base so that it may be set with its inner end disposed at any selected cell from which pins are to be removed. Thus, after once locating the proper size pins to be used, it is an easy matter to locate the proper cell whenever a pin is to be withdrawn therefrom.

With the foregoing in view, the invention resides in the novel subject matter heroinafter described and claimed, the description being supplemented by the accompanying drawings.

Fig. 1 is a perspective view of a tool constructed in accordance with my invention, showing it as used for removing a pin from a portion of a piano action;

I Fig. 2 is a central vertical longitudinal section, partly in elevation; and

3 is a transverse sectional view on line 33 of Fig. 2.

In the drawings above briefly described which illustrate the prelerred form of con traction, the numeral designates a horizontally elongated, rectangular, base block which may be formed of wood or metal, desired. Near its upper surface, the opposed sides of this block a are formed with longitudinal guide grooves 5 for a purpose to appear, and near one of its ends, said block is formed with a pin-receiving socket 6 and with a post receiving socket '7, both of which open through the upper face of the block. The remainder of the length of the block t is occupied by cells 8 which open through its upper side and are intended to contain {hinge pins of different sizes, and if desired, the sizes of the pins may be stamped or otherwise provided on the block, adjacent the cells.

An elongated cover plate 9 is provided for the cells 8, said plate having angular side 'i'langes 1.0 slidably and trictionally received in the grooves 5 and being provided al o with a suitable handle 11. After first determining the proper size of the pins to be used on any repair job, the cover plate may be set so that its inner end is disposed adjacent the cell 8, containing pins of that size. Thus, the repair man knows that each time a pin is to be removed from a cell, it should be taken from the particular cell at the inner end of the cover plate 9. Thus, it is practically insured that all of the pins which he removes for use, shall be of the proper site.

An anvil plate 12 rests upon the end port on of the base block 4, which is provided with the sockets 6 and 7, and said plate is provided with openings 13 and 14 aligned with thes sockets respectively. The side edges of the plate 12 are provided with angular flanges 15 which engage the grooves 5 so as to hold the plate against upward movement with respect to the base block l. Longitudinal movement oi this anvil plate upon the base block, is prevented by a vertical. post 16 which passes through the opening l t and is threaded or otherwise secured in the socket 7. When the post is removed however, one anvil plate may be slid from the base block l and another anvil plate substituted, should this be advisable, for instance due to accidental injury to the plate previously in use.

A lever 17, having any desired handle such that indicated at 18, is lulcrumed at 19 the upper end of the post 16, and a punch is pivoted at 21 to said lever 17, the lower end of said punch terminating in a pin-like portion 22 which is aligned with the socket (5 and the opening so that it may be used to force a flange pin from a portion A of a piano action, as will be clear from Fig ures 1 and 2, the pin being forced into the socket 6, as it is depressed out of the position which it previously occupied.

hen fitting new pins in place, it is often necessary that they be out to the proper length. For this purpose, I have shown fixed and movable cutters 23 and 24 carried by the post 16 and the lever 17 respectively.

In addition to the advantages above pointed out. attention may be invited to the fact that when the cover plate 9 is closed, it abuts and is flush with the upper side of the anvil plate 12. Thus, the two plates form a single smooth surface upon which to rest the portion of the action, from which the flange pin is to be removed. In addition to. this, the plate 9 normally closes the flange pin cells, but gives access to them Whenever desired.

On-account of the advantages existing from the details disclosed, they are preterably followed. However, within the scope of the invention as claimed, variations may be, made.

I claim 1. A flangepin remover comprising a base block having a post-receiving socket and a pin-receiving socket both of which open through its upper surface, the opposed vertical sides of said block being formed with longitudinal guides, an anvil plate resting on said book and having down-turned,

flanges engaged with said guides, said plate being formed with a pin-receiving opening and a post-receiving opening alined with the corresponding sockets of the block, and punch-carrying and operatmg means lncluding a post fitting into said post-receiving opening and socket and holding said anvil plate against sliding upon the block.

2. A device of the class described comprising a horizontally elongated base block having a plurality of cells spaced apart along its length and opening through its upper face, said cells being intended to contain flange pins of; different sizes, and a cover plate for said cells hai ing a frictional sliding connection with said base block, said cover plate being slidable longitudinally 0t said block, whereby its inner end may be set at any selected cell from which pins are to be used.

A device of the class described comprising an elongated base recessed to receive flange pins. pin-removing means operatively connected with said base and movable downwardly toward the same, and a metal cover for said base formed of sections whose upper sides are flush to support the work, one of said sections being a cover for the recessed portion of the base and being movably mounted to give access to the contained flange pins.

In testimony whereof I have hereunto affixed my signature.

ALBERT M. HUGHES.
